The invention relates to improvements in coling retorts for the destructive distillation of coal as described in the present specication and shown in the accompanying draw-k 5 ings which form part of the same. g i

The invention appertains to a colring retort for treating coal in twoV distinctive vsteps orV stages, the first being. the subjecting of the coal to an external application of heat in orio-der to vdrive o the'gaseous and vaporous products, the second'being the injectionor diffusion of superheated steam throughout Ythe coal in order to complete vthe colring process.

The invention has for its objectiprimarily fto provide an efficient cokingretort'of the type described, one which will facilitateand expeditethedistillation of; coal: more particularly the invention comprehends a digester 20 embodying a band like coal chamber for the purpose of holding a thin vertical wallof coal which issurrounded both o n the outside and inside and also on the top with` superheating chambers whereby armaximuml of 25 heating surface is obtained for a' givenfmass of coalresulting amore thorough andv ,complete coal distillation.

With these and other obj ectsin view, the

invention consistsV of the novel construction l 3o and arrangement of a colring retort as de fvie'w taken Figure 5 isa fragmentary view'of thelower portion of the colring retort viewed endwise.

and showing the particular constructionof` the drop bottom. *Y

Like numerals of `reference .indicate corresponding parts in each of the figures throughout the drawings. 1 Y 1 In the drawings, the cokingretort takesthe form of a rectangularshaped memberin ele- 5o vaton which invcross section iscornpa'rative#v ly narrow andhas its ends roundedof in semi-circles asclearly seen in lFigures 1 and 3. The colr-ingcretortis provided with an Voutside shell or walllO,y an intermediatewall Y 11, and an inner-wall 12, which provide an intermediate vertical coalchamber 13 surrounded by anoutside superh'eating chamber 14 and, an inside superheatingchamber 15. The outside st'e am chamber communicates withthe space 16 provided between a Vdouble PATENr oFFIcE walled top butis isolated-from the inter-l l mediate and inner chambers.'

VThe coal chamber hasa drop bottom 17V which will be hereinafter more fullyv de scribed;` The inner chamber 15 is isolated l fromY the other chambers andis dividedinto two` parts by a longitudinal baiilefl.- This bathe assists fin strengthening the inner steam chamber 15in addition to functioning to `proe vvide double compartments i whereby jsteam mayze'nter oneand then pass into Ythe other.

of spacers 19v consisting vof short bars having their'ends rigidly secured to vwalls 10 and 11'.

1 Inthevicinity of thetop ofthe colring re` tort 2O and on veach side isa charging door 21 VThe coal chamber is rigidly braced to the outer shell or wall 1() Vbyy means of a plurality ofco-nventionaldesign. which charging door Y' leads into thev coalvr chambers as at 22 andv is 4isolatedsfrom the outer steam chamber 14.v

Similarly,l oneach sidev ofthe k coking retort andA preferably at V the same height .as the charging doors is an egress Y2 3 which connects with piping leading tothe apparatus vfor the fractionation of Vfthe. volatile matter driven ofi from VVthe Vcoal; These :passages for the outlet :l iby-products A are likewise isolated from the chamber 14 asiat 24 Figure 3. i

Superheated steamf is piped toY the outer chamberA 14 through alvalve-controlled pipe.

Superheatedlfsteamis piped to. one division of the inner vchamber through apipe-27 which passes vertically downwardlythroughthe topof the coking retort and extends downwardlyA jthrQilghJth inner chamber .159511 one aid' Ot ity of apertures 29 provided in the lower end of the baiile' V18 tothe other half or compartment of this inner chamber andis yconducted from there through a'pipe AOleading outside of the Ycoking retort. A distinctive advantage of having the pipes 27 and() extend to the Vicinity ofthe bottom ofthe chamber is lthat they can be used to siphon off water resultant from the condensation of the steam incidental to the operation of theeolring retort.'

y vIn order to diffuse superheated steam into theeoal in the second step, downwardly extending perforated pipes 31- are supplied, there' 'beingpreferably six in number as shown in the accompanyingdrawings, which vpipes extendV through the top of the coling retort and are'isolated froi'nxthe superheating tn ljiambers" Vr 'In order to eject the residual mass after conipletionof ythe eking `process a ram connected to rods, `four in number, which extend externally fof the co'ling retort for attachment tofhydraulical cylinders orother oper'ating means which are conventio-nal'to u i ll tll,

The drop bottom 17 consists of a door provided withl a circumferential flange 34- beveled as 'at 35 for theV purpose 'of abutting an oppositely beveled edge of the bottom of the coal chamber opening. This engagement ofthe beveled edges provides avery evcientl seal i against leakage ofthe products distilled from thecoal. 'The'door is hinged at one endv as at 35"V and 1s secured when closed bymeans of locking devices y36 which locking devices con- TSi'st of lugs??? rigidly projecting from the sary'to sl'aeken .the setsorewe'o, swing the yoke o shell of thecoking retort 'and carryingyokes 38 which are pivoted at-39 in order that they may swingk outwardly. VThese yokes are Vdisr posed toslipjover arms 39 integrally proj'ecting lfrom the sides yof the door. Each yoke carries `a setscrew 40 on its freefend which is tightened for -the purpose Of'pbe-arimg Vagainst Vthe armBQ s 'o asto Vpress the door u, firmly against the bottom of thel'coking retort, To .drop lthe door itis merelyneces- 38 outwardly fionathe-r door so as to free it t from engagement with 'the arm '39 which a1-k flows'thedoorto dr.'
